My employer switched to dell laptops, the first gen xps 15 and 13s, and now the precisions. As they get older we're seeing more and more battery swell. We're not sure the root cause, we speculate that it's a specific usage pattern related to the USB-C docks everyone has. Your battery is definitely not okay, you should get it replaced asap. We've looked at some alternatives like the hp spectre, or the lenovo ideapad and the asus zenbook, but none of the felt as nice as the precision line wrt build quality and bang-for-buck.
